How to edit my rex search to extract two different or duplicate IP addresses at the same time?

Current search:

search "xxx" | rex field=_raw "api:(?\s\d+.\d+.\d+.\d+)"

I'm using the rex command, but it does not return the expected result when there are two IP addresses.

If both IPs are in the same event with "api" before it, you can use max_match, like this

search "xxx" | rex max_match=0 field=_raw "api:\s?(?<IP>\d+.\d+.\d+.\d+)" | mvexpand IP | table IP

If they are not in the same event, will need to see some sample events.
